PROBLEM TO BE SOLVED: To simultaneously satisfy a request for power generation and a request for a suction air quantity of an engine, in a system for recovering electric power from a displacement supercharger rotating by suction negative pressure. SOLUTION: This control device has a rotor 4 interposed in an intake passage 2, a generator 4a connected to a rotary shaft of the rotor 4 and generating electric power by rotating the rotor 4 by the suction negative pressure, a power generation quantity control means 9 for controlling a power generation quantity of the generator in response to a power generation request for a vehicle, a bypass passage 3 for flowing intake air by bypassing the generator 4a, a bypass valve 6 arranged in the bypass passage 3, an actual manifold internal pressure detecting means 20 for detecting pressure in an intake manifold of an engine, a request intake pipe internal pressure calculating means 9 for calculating pressure in the intake manifold corresponding to an air quantity requested by the engine, and a control means 9 for controlling opening of the bypass valve on the basis of actual manifold internal pressure and request intake pipe internal pressure.
